Hispania, 68 BC. Facing trouble in the Ninth, with mutinous troops and a vicious new commander, Marcus Falerius Fronto finds refuge with the Governor of Hispania Citerior and a solution to his problems there.
But to save his career and his legion, he faces a mammoth task: to bring a rebellion in the mountains to a close. Part of the Vascones has decided to resist Roman occupation under a brutal new chief who calls himself The Ghost.
Commanding a strange and disparate force of soldiers, natives and retirees, Fronto must march into territories unknown, wrest harsh lands off dangerous tribes, and finally face the King of the Mountains.
